Forces True or False (1 point Each) 1. An object atestatays at rest does not stay at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. 2. One good example of inertia is blood rushing from your head to your feet while quickly stopping when riding on a descending elevator. 3. The definition of inertia is the resistance an object has to a change in its state of motion 4. Newton's first law of motion declares that a force is needed to keep an object in motion. 5. Mass is that quantity that is solely dependent upon the inertia of an object. 6. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will accelerate. 7. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction. & A force is a push or pull upon an object resulting from the object's interaction with another object. 9. Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. 10. Formally stated, Newton's third law is for every action, there is an equal and opposite reaction. 11. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. 12. 9.79546 m/s/s is the acceleration due to gravity for Birmingham, AL according to the Physics Classroom Website used in class. 13. Forces always come in pairs- known as "action reaction force pairs." 14. Friction always opposes motion, and is directly proportional to the size of the normal force. 15. Any vector that is directed at an angle to the customary coordinate axis can be considered to have two parts-each part being directed along one of the axes-either horizontally or vertically. 16. If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 9.8 m/s/s. Objects at equilibrium must have an acceleration of 9.8 m/s/s 17. If there is an acceleration for an object being pulled across a floor, then it is a horizontal acceleration; and thus the only imbalance of force would be in the horizontal direction. 18. Objects are known to accelerate down inclined planes because of an unbalanced force.
